Has anyone had experience using the small 7 gallon stainless conical ferminters available? I am having good luck using carboys, but would like to simplify the brewing process and reduce the risk of contamination or oxidation. This seems to be a good solution, but would like input before spending that much money.

I own one. It's o.k. nothing more. The yeast settles on the shoulder of the carboy.
So you have to "twist" the carboy back an forth, to get the yeast to settle.
I also lost a lot of beer, trying to clear off the trub.

Last year my lovely wife bought me a Mini-Brew conical from the homebrew shop for about $100.00. It's a plastic conical; please save snickering for last , holds 6.5 gallons; easily enough to make a FULL 5 gallon batch, is alittle over 3' tall, and has two stainless ball valves for trub removal; bottom, and hydro readings; about 10" up the side of the 45 degree slant. The system works great. The plastic is a polymer that is alittle more than 1/8 inch and alittle less than 1/4 inch thick; use a standard rag to clean and it will never scratch. Every thrid time I use a cleaner, but normally alittle bleach does fine. The only thing is that the trub tends to stick to the slanted walls, but a few taps with the handle of a kitchen knife knocks it loose real quick. It has a BIG hole at the top for easy cleaning, and all edges are rounded for easy cleaning. Anyhoo, for a one bedroom apartment, shallow in the pocket book, brewer like me it's a WINNER!!!! Stainless rules I know, but the other is a usable solution.

The Fermentap looks very good on paper but actually works very poorly. The sides are not steep enough to have the trub truly settle to the bottom. Your opening to remove trub is a racking tube which is entirely to small so it clogs easily and often. If you want something that will be a conversation piece and look impressive until you use it - buy it. Otherwise save your money and make another batch.

I just ordered the mini-brew 10 gal conical $225. I already own their mash/lauter tun.
Why everyone gets so !@#$ crazy about plastic scratching,,,i don't know. What kind of stirrers are u using? A chain saw.
Stainless looks nice. I'll let u all know how the fermentor works after I use it.
